摘要： Provided is a valve that can be closed with a small driving force. A valve V1 includes: a valve housing 10 provided with a primary pressure port 41a and a secondary pressure port 11; a valve body 51 configured to be driven by a solenoid 80; a valve seat on which the valve body 51 is seated; and a spring 85 that urges the valve body 51 in a valve opening direction. The valve seat includes a first valve seat 10a and a second valve seat 40a disposed on a radially inner side of the first valve seat 10a. The second valve seat 40a is configured for moving in a direction toward the valve body 51 due to a differential pressure between a primary pressure and a secondary pressure.

摘要： To provide a capacity control valve having good responsiveness for a differential pressure. A capacity control valve V includes a valve housing 10, a primary valve 50 opened and closed by a driving force of a solenoid 80, a pressure-sensitive valve 53 opened and closed by a pressure of a pressure-sensitive chamber 40, and a differential pressure valve 90 opened and closed by a differential pressure valve body 91 moved by a pressure. A control port 14 and a suction port 13 can communicate with each other through an intermediate communication path 55 by opening and closing the pressure-sensitive valve 53. An adapter 70 is provided with an accommodation portion 70d accommodating a differential pressure valve body 91, a pressure introduction path 70e communicating the control port 14 with the accommodation portion 70d, and a differential pressure communication path 70f communicating the control port 14 with the suction port 13 when opening the differential pressure valve 90. A first urging member 92 and a second urging member 93 are interposed in the accommodation portion 70d on both sides of the differential pressure valve 90 in an opening and closing direction with the differential pressure valve body 91 interposed therebetween.

摘要： There is provided a valve having high controllability. A valve V1 includes a valve housing 10 provided with an inlet port 40b and an outlet port 11; a valve body 51 configured to be driven by a drive source 80; a spring 85 that urges the valve body 51 in a direction opposite a direction of driving by the drive source 80. A valve seat 40a is formed at an edge of a through-flow passage 40b. The valve body 51 and the valve seat 40a forms a poppet valve that controls a flow rate in accordance with a movement of the valve body 51. A flow passage C1 on a downstream side of the poppet valve 50 is provided with a reduction region where a flow passage cross-sectional area tends to decrease toward a downstream side.
